Abstract (en)

[origin: WO2022096464A1] The invention relates to a method for operating an injector (7) on an internal combustion engine (1), wherein: • - fuel is introduced into a combustion chamber (3) of the internal combustion engine (1) by means of the injector (7); • - for each of a plurality of introduction events, a wear value for the injector (7) is captured; • - each captured wear value is assigned to one wear value class of a plurality of wear value classes; • - for each wear value class of the plurality of wear value classes, a class frequency of the captured wear values assigned to the wear value class is determined; • - a total wear value for the injector (7) is calculated on the basis of the class frequencies of the wear value classes; and • - an injector condition of the injector (7) is evaluated on the basis of the total wear value.
